California began to take action statewide, forming a Bureau of Air Sanitation within the California Department of Public Health, and requiring that department to establish air quality standards and set necessary controls on motor vehicle emissions of air pollutants. In California established the first tailpipe emissions standards in the nation. A year later the California Air Resources Board was established.

That was just the beginning. Under the provisions of the Clean Air Act, CARB has adopted, implemented and enforced a wide array of nation-leading air pollution controls, based on a strong foundation of science over the next five decades. This regulatory history reflects a longstanding partnership between state and federal air quality regulators during both Republican and Democratic presidential administrations. This partnership has allowed California to develop and implement air pollution control strategies that have proven to be a model for other states, the nation and other countries.

Some of the innovative vehicle emission control strategies that have led to cleaner air in California include:.

CARB, which had already eliminated lead in gasoline, adopted standards for cleaner-burning gasoline, as well as initial standards for cleaner diesel fuel for trucks and buses. CARB also began work to reduce smog-forming emissions from thousands of common household products. In the s, CARB became responsible for monitoring and reducing greenhouse gas emissions that cause climate change.

AB 32 established a first-in-the-world comprehensive program of regulatory and market mechanisms to achieve real, quantifiable, cost-effective reductions in greenhouse gases. In the current decade, California solidified its position as a world leader on climate change, entering into climate agreements with several nations and linking cap-and-trade programs with Quebec.

Its broad range of programs to reduce greenhouse gases addresses every major sector of the economy including a Zero Emission Vehicle mandate that will clean up the transportation sector and put close to 1. Trump at the time will be traveling in California, where he is scheduled to attend fund-raisers in Los Angeles and Silicon Valley.

Lawyers said the action takes the administration into uncharted legal territory in its battle with the state, which has vowed to fight the change all the way to the Supreme Court. In a speech on Tuesday, Andrew Wheeler, the head of the E. On Wednesday morning, Mr.

The attack on California is only the latest in a broad array of efforts to weaken climate change regulations by a president who has repeatedly expressed skepticism about the scientific consensus that global warming is human-caused. The administration plans to weaken auto emissions standards nationwide , has rolled back rules governing coal-burning power plants and eased restrictions on energy companies governing leaks of methane , a powerful greenhouse gas.

A revocation of the California waiver would have national significance.

Legal experts said that if Mr. If it was rejected by the Supreme Court, it would allow states to set separate tailpipe pollution standards from those set by the federal government. The outcome could split the United States auto market, with some states adhering to stricter pollution standards than others.

For automakers, that would be a nightmare. A spokesman for the E. Wheeler said the administration would soon be moving ahead with a single national vehicle pollution standard, suggesting that it would include the California revocation.
